Custom Window Sizes for Older Baltimore Rowhouse Openings

A window that is close but not quite right can leave gaps, create draft problems, complicate flashing, and make the finished job look forced.

The real job is to match the opening, protect the structure, preserve the proportions, and choose a window that works in Baltimore’s weather and in the way these houses were originally built.
